The Ductus Arteriosus,

Archives of Internal Medicine, 1975
In his monograph, Cassels provides an extensive discussion of the patent ductus arteriosus from almost every conceivable aspect. There are chapters dealing with ductal embryology, anatomy and histology, physiology, and clinical correlations. The author also deals with the patent ductus arteriosus in association with other cardiac defects, pulmonary ...

The silent ductus arteriosus

The Journal of Pediatrics, 1978
Preterm infants at risk of developing a patent ductus arteriosus were followed sequentially by physical examination, echocardiographic determinations of the LA/AO ratio, and chest roentgenograms. The results show that a significant number of infants who have no clinical signs or symptoms of a PDA have large left-to-right shunts.

Pharmacotherapy for patent ductus arteriosus closure

Congenital Heart Disease, 2018
Even though up to 60% of premature infants less than 28 weeks gestation develop persistent patent ductus arteriosus (PDA), there remains controversy regarding if, when, and how to close the PDA.

Comparative physiology of the ductus arteriosus among vertebrates.

Seminars in Perinatology, 2018
The ductus arteriosus is typically viewed as a mammalian fetal blood vessel providing a right-to-left shunt of right ventricular outflow away from the lungs and to the systemic circuit, that must close at birth.

The ductus arteriosus

Fetal and Maternal Medicine Review, 1990
The ductus arteriosus is a large vessel which connects the pulmonary trunk with the aorta. During fetal life it serves together with the foramen ovale as a shunt at cardiac level. Due to a complex regulatory mechanism it is capable of maintaining patency during fetal life and of rapid closure after birth.

Surfactant and patent ductus arteriosus [PDF]

open access: possibleThe Indian Journal of Pediatrics, 2010
To investigate the relationship between surfactant replacement therapy and the development of a haemodynamically significant ductus arteriosus.All premature infants at 28-32 wk gestation with a clinical diagnosis of respiratory distress syndrome were retrospectively reviewed and subdivided into two groups; intubated, mechanically ventilated and ...

Patent Ductus Arteriosus

Cardiology Clinics, 2013
Patent ductus arteriosus in adults is usually an isolated lesion with a small to moderate degree of shunt, as a larger shunt becomes symptomatic earlier in childhood. The classic murmur of patent ductus arteriosus may be the first clue to its presence, or it may be detected accidently by transthoracic echocardiography, computed tomography, or magnetic ...

Persistierender Ductus arteriosus [PDF]

open access: possible, 1982
Der persistierende Ductus arteriosus ist eine angeborene Gefasanomalie, bei der es sich um eine Kommunikation zwischen Aorta und Truncus pulmonalis, somit um eine arteriovenose Fistel zwischen Korper- und Lungenkreislauf, handelt.

Aneurysm of the ductus arteriosus in a heifer

Veterinary Record, 2005
The paper describes clinical, radiological, ultrasonographic and pathological findings of an aneurysm of the ductus arteriosus in a heifer. The pathogenesis of the present ductus arteriosus aneurysm, unusually characterised by a thick internal, multiple layer of blood embedded in fibrin and fibrotic organisation, is unclear.

The Response of the Ductus Arteriosus to Prostaglandins

Canadian Journal of Physiology and Pharmacology, 1973
Effects of various prostaglandin types on strips of lamb ductus arteriosus were investigated under anaerobic and aerobic conditions. Prostaglandins E1 and E2 relaxed markedly the anoxic ductus over a dose range from 10−9 to 10−5 M whereas they had little or no effect on the tissue after exposure to oxygen.
